尝试以下步骤后关于 Acer 笔记本电脑的帖子但最后一步是这样完成的：
sudo mv /home/******/ath10k-firmware/QCA9377/hw1.0/WLAN.TF.1.0/firmware-5.bin_WLAN.TF.1.0-00002-QCATFSWPZ-5 firmware-5.bin
因为在建议的目录中没有找到该文件。
重新启动网络小程序后甚至不显示启用 Wi-Fi 选项。

确保您拥有最新的固件。请打开终端并执行以下操作：
cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.3_all.deb
sudo dpkg -i linux*.deb
重新启动并告诉我们是否有任何改进。
编辑：您的无线已被硬件阻止：
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: yes
找到并按下无线开关，有时也称为飞行模式。
如果按下按钮没有任何变化，请尝试：
sudo modprobe -r ideapad_laptop
无线网络现在可以用了吗？如果可以，让我们让它持久化：
sudo -i
echo "blacklist ideapad_laptop" >> /etc/modprobe.d/blacklist.conf
exit
